    A thin-film PPLN waveguide for second-harmonic generation at 2-µm. Lin Chang1,*, Nicolas Volet1, Yifei Li1, Jon Peters1, and John E. Bowers1. 1Department of Electrical and Computer Engineering, University of California, Santa Barbara, CA , USA *[email protected] Abstract: We present a thin-film periodically-poled lithium niobate (PPLN) wavelength converterFile Size: KB. Abstract: We have demonstrated a broadband waveguide polariser with high extinction ratio on a polymer optical waveguide coated with graphene oxide via the drop-casting method. The highest extinction ratio of nearly 40 dB is measured at nm, with a variation of dB across a wavelength range from nm to nm, a ratio that is (to our knowledge) the highest reported for graphene.
